Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-browse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Web Browse: open a real page for the user to look at

Your PRIMARY way to open a page in the dashboard's Browser panel is the browser MCP tool — it drives the built-in Electron panel in-process, with no separate Chromium and no macOS security prompt:

browser(op="navigate", args={"url": "https://example.com"})

Other ops: snapshot (get element refs), then click / type / press_key / hover / select_option / screenshot / wait_for / back / console. Call snapshot first to get refs before a click/type.

If the tool returns guidance that no native panel is serving this session (a remote gateway, or a plain-browser dashboard with no Electron panel), THEN fall back to playwright-cli (below). Do not reach for playwright-cli first: on the desktop app it spawns its own unsigned Chromium and triggers a macOS security prompt, and the user is watching the built-in panel, not that window.

Fallback (and attach / logged-in sessions): playwright-cli

The dashboard's right-side Browser panel also shows a live playwright-cli session. When the browser tool reports no native panel — or you need an attached browser carrying the user's real logins — open a page with:

playwright-cli open https://example.com

The page loads in the session, the panel surfaces it, and the command prints the page URL, the page title, and a path to a snapshot YAML.

This is the view path. It is deliberately narrow: open the URL and show it, nothing more.

What you get back, and what to do with it

One command prints roughly three lines. That is usually the whole answer for this skill: the URL and title confirm the page loaded, so you do not need the snapshot at all.

  • Open the snapshot YAML only when you need the tree (you are about to click something, or the user asked what is on the page). Read it with your own file tools, at the exact path printed. Do not guess a path.
  • You do not need a screenshot to make the page appear. open alone shows it. Screenshot only when you need to inspect the rendering, which is the web-verify skill's job.
  • A screenshot is not what the user sees. They are watching the live session.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
